In data transmission Manchester encoding is a method of transmitting bits that allows the receiver to easily synchronize with the sender. Manchester encoding splits each bit period into two, and ensures that there is always a transition between the signal levels in the middle of each bit. In Manchester encoding "1" is transmitted as 0 in the first half of the clock and 1 in the second half of the clock. And "0" is transmitted as 1 in the first half of the clock and 0 in the second half of the clock


Differential Manchester encoding is a line code in which data and clock signals are combined to form a single 2-level self-synchronizing data stream. It is a diferential encoding, using the presence or absence of transitions to indicate logical value. It is not necessary to know the polarity of the sent signal since the information is not kept in the actual values of the voltage but in their change: in other words it does not matter whether a logical 1 or 0 is received, but only whether the polarity is the same or different from the previous value; this makes synchronization easier.
